IMPROVEMENT IN SHAPING THE HEELS OF BOOTS AND SHOES.

Specification forming part of Letters Patent No. 43,082, dated June 14, 1864.

.To all whom it may concern,.-

Be it known that I, EBEN J. BEA-NE, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful ImprovementI in Machines for Trim min gor Shaping the Heels of Boots and Shoes; :rnd I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a side elevation and section of the machine to which my improvement is to be applied. Fig; 2 represents my improvement detached from the machine. Fig. 3 is a front view of the cutter-head G detached. Fig. 4 is a view of the pattern I detached.

Similar lettersindicate corresponding parts in all the figures.

My invention consists in arranging with a cutter, as hereinafter described, for shaping the heels of boots and shoes, a ridged or gaging roller and a yielding center-stud, as hereinafter described.

The machine to which my improvement is directly applicable is shown in Fig. l of the drawings, in which Ais the frame, consisting of two upright columns ascending from the bed-plate A', in which are formed suitable bearings for the main shaft C, which is revolved by means of the pulley n thereon. The cutter-head G is arranged on one end of the shaft C, and consists of a number of blades, Z, of the shape necessary to give the desired form to the heel, and are rinly secured to the metal head G by screws e e, as shown in Fig. 2. Upon the side of the cutter-head next to the frame is fitted a loose washer or disk, E, turning freely on the main shaft, the office ot' which is to act in concert with a patternp1ate,.I, Fig. 4, to which the boot-heel is secured to govern the movements of the cutterhead in determining the shape of the heel. Upon the other side of the cutter-head is art ranged a gaging-roller, d, formed with a ridge,

a center-stud, g, upon 011e side thereof in a sliding plate, J, and I employ a spring, i, in connection with such center pin or stud to press it forward and give the stud a yielding action, so that when the ridge t of the rolhr l is in the groove between the counter and the base of the heel the center-stud may be depressed sufficiently to afford an axis for the heel to turn upon, which will adapt itself to any variation in the height of different heels.

From the sliding plate J an arm, B extends, in the end of which is formed a bearing for a centering-pin, p, on the end of a screw-arbor, which is advanced or withdrawn from the center-stud g when it is desirable (in inserting and removing the shoe from the machine) by means of the hand-wheel D, and the said .centering-pin p is raised and depressed to adjust the heel to be trimmed to the action of the cutter by means of the hand-lever N and its connecting-rod y. Thus arranged, the sliding plate and the parts above described as attached thereto slide vertically in suitable guides formed in the column A2 against the action of the spring X and independently ot the cutter-head G, which revolves steadily in one position, the sliding-movement being produced by means of a treadle arranged beneath the machine and connected to the plate J by a rod in such a manner that by depressing the treadle the heel, which is held by the centerstud g and centering-pin p, is withdrawn from the cutter-head, and when the treadle is released the pressure of the spring .X carries the heel up to the cutter-head and the patternplate up against the roller-disk E when the heel is revolving with the pattern-plate upon the stud g. While the cutter-head is revolving rapidly the heel is trimmed smoothly to the shape of the pattern-plate.

I, Figs. 2 and 4, is the pattern plate, formed with a hole, r, which receives the end ot' the center-stud g, and furnished with a number ot' spurs, V V V, by means of which the plate is fastened to the heel to be trimmed. It will be perceived that the portion of the plate which is in contact with the bottom of the heel is narrower than the pattern portion I, which is intended to allow the cutters to be wider than the height of the heel, in order to cnt the leather away clean to the face of the heel and to admit of trimming heels of various heightsA The several parts being constructed and arranged as described, the operation is that the plate I is fastened to the heel of the boot or shoe by driving the spurs V V V into the face thereof by a smart blow with a mallet. The plate is then placed on the centerstud g, and the centering-pin p is screwed up against the last with in the boot or shoe, and the centerstud g thereby depressed sufficiently to place the ridge t of the gage-roller in the groove at the base of the heel and give thelatter the proper position relatively With the cutter l,

which being done while the cutter-head is re! volving rapidly with the patternedge I of Vthe pattern-plate bea-ring against theroller E, the pattern and shoe are turned on the center stud and pin p and the edge of the heel brought against the cutters, and by this means the superiiuous leather is trimmed off and the heel is brought to its proper shape, Whether the heel be a trie higher or lower, the yielding of the center-stud g accommodating any usual variation in that respect.

I am aware that a similar arrangement of a heel-plate, centering pin, and rotary cutters has been previously patented,but with out being combined with the equivalent of the ridged gaging-rollcr d, and Without any yielding movement of the center pin vor stud, which are the distinguishing features of my improvement, and the means by 4which 1 am enabled to do a greater variety of Work on the same machine, and to trim the heel so smoothly and completely as to require no further finishing by hand, as is the case with the arrangement referred to.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

The combination of a cutter, substantially as described, with a ridged or gaging roller, d, and a yielding center-stud, g, substantially as described, for the purpose specified.
